ABSTRACT Dicynodont therapsids are prominent elements of Triassic continental faunas, but the date of their demise is controversial, linked either to end-Carnian faunal turnover or to end-Triassic mass extinction. The second timing is based on a unique, giant dicynodont-theropod dinosaur fauna from Lipie Śląskie, Poland, thought to be Rhaetian in age, due to conjectural botanical and conchostracan (but not tetrapod) evidence. On the other hand, an age assignment for the Lipie fauna to the mid…

Extinction and dawn of the modern world in the Carnian (Late Triassic)
A meta-analysis of fossil data suggests that the Carnian Pluvial Episode was linked to a major extinction event and might have been the trigger of the spectacular radiation of many key groups that dominate modern ecosystems.
The Late Triassic Extinction at the Norian/Rhaetian boundary: Biotic evidence and geochemical signature
Abstract The latest Triassic was an interval of prolonged biotic extinction culminating in the end-Triassic Extinction (ETE). The ETE is now associated with a perturbation of the global carbon cycle
First Occurrence of Doswellia cf. D. Kaltenbachi (Archosauriformes) from the Late Triassic (Middle Norian) Chinle Formation of Arizona and Its Implications on Proposed Biostratigraphic Correlations across North America during the Late Triassic
ABSTRACT Doswellia kaltenbachi is a long-snouted non-archosaur archosauriform known from the Late Triassic of the United States (Virginia and Texas). New material from the Chinle Formation of Arizona
Middle Triassic Pentasauropus-dominated ichnofauna from western Gondwana: Ichnotaxonomy, palaeoenvironment, biostratigraphy and palaeobiogeography
Abstract Quadruped trackways of large pentadactyl footprints are reported from the Middle Triassic (Anisian-Ladinian) Cerro de las Cabras Formation of the Cuyo Basin, Mendoza Province,
The late Triassic development of playa, gilgai floodplain, and fluvial environments from Upper Silesia, southern Poland
Abstract The numerous discoveries of disintegrated skeletons of large terrestrial vertebrates within several thin levels of the Upper Silesian Keuper initiated broad investigations into the
Nonmarine Mass Extinctions
Abstract. A critical review of putative nonmarine mass extinctions associated with the so-called “Big 5 mass extinctions” of marine invertebrates (Late Ordovician, Late Devonian, end Permian, end
Niche partitioning shaped herbivore macroevolution through the early Mesozoic
This work identifies five main herbivore guilds (ingestion generalists, prehension specialists, durophagous specialists, shearing pulpers, and heavy oral processors), and finds that herbivor clades generally avoided competition by almost exclusively occupying different guilds.
The youngest detrital zircons from the Upper Triassic Lipie Śląskie (Lisowice) continental deposits (Poland): Implications for the maximum depositional age of the Lisowice bone-bearing horizon
Abstract The Lisowice vertebrate hard-part-bearing horizon, cropping out of the Lipie Śląskie clay-pit, is one of the most famous Keuper Lagerstatte (Upper Silesia, Poland, Europe). The horizon has

Sickle cell disease is induced by a mutation that converts normal adult hemoglobin to sickle hemoglobin (HbS) and engenders intracellular polymerization of deoxy-HbS and erythrocyte sickling.


A Dicynodont-Theropod Association in the Latest Triassic of Poland
It is generally accepted that during the Triassic the composi− tion of tetrapod faunas underwent a series of fundamental transformations, mainly as a result of diversification of archosaurs and
A new dicynodont–archosaur assemblage from the Late Triassic (Carnian) of Poland
ABSTRACT This paper reports a new assemblage from the Late Triassic (mid–late Carnian) at Woźniki near Częstochowa (Poland). The Woźniki vertebrate assemblage is similar to that of Lisowice–Lipie
Global Taxonomic Diversity of Anomodonts (Tetrapoda, Therapsida) and the Terrestrial Rock Record Across the Permian-Triassic Boundary
Investigation of diversity patterns in Anomodontia, an extinct group of therapsid synapsids (‘mammal-like reptiles’), through time and in particular across this event finds it remains unclear whether the Middle Triassic extinction represents a gradual or abrupt event that is unique to anommodonts or more common among terrestrial tetrapods.
First records of diapsid Palacrodon from the Norian, Late Triassic Chinle Formation of Arizona, and their biogeographic implications
Vertebrates from the Triassic Period have broadly disparate tooth shapes and dentition patterns, the result of intense morphospace experimentation following the Permo-Triassic extinction. Here, we
Basal dinosauriform and theropod dinosaurs from the mid–late Norian (Late Triassic) of Poland: implications for Triassic dinosaur evolution and distribution
The rise of dinosaurs during the Triassic is a widely studied evolutionary radiation, but there are still many unanswered questions about early dinosaur evolution and biogeography that are hampered
Triassic environments, climates and reptile evolution
Abstract A consideration of all the available data on Triassic vertebrate faunas, and their stratigraphic location reveals a relatively sudden extinction event among the last of the mammal-like
The origin and early radiation of dinosaurs
Abstract Dinosaurs were remarkably successful during the Mesozoic and one subgroup, birds, remain an important component of modern ecosystems. Although the extinction of non-avian dinosaurs at the
Dinosaur Success in the Triassic: A Noncompetitive Ecological Model

There is no evidence that either thecodontians or dinosaur demonstrated their superiority over mammal-like reptiles in massive competitive take-overs in the latest Triassic, and explanations of dinosaur success based on the competitive superiority of their thermoregulation or locomotory capability are unnecessary.
Age and correlation of Late Triassic tetrapods from southern Poland
Age assignments of Triassic tetrapod fossils can be achieved by direct reference to a scheme of Triassic land-vertebrate faunachrons (LVFs) that correlates Triassic tetrapod fossil assemblages to

The fossil record of Late Triassic tetrapods can be organized biostratigraphically and biochronologically into five, temporally successive land-vertebrate faunachrons (LVFs) that encompass Late
